Definitions

  • the present invention relates generally to bone augmentation and in particular an apparatus for performing bone augmentation.
  • Vertebroplasty is a well-known procedure for augmenting a vertebrae that has collapsed due to osteoporosis or other indication. See, for example, U.S. Pat. No. 6,273,916 to Murphy (“Murphy #1”) and issued Aug. 14, 2001, the contents of which are incorporated herein by reference.
  • vertebroplasty involves transpedicular or posterolateral injection of a bone cement into the vertebral body.
  • bone cements can be used.
  • One common bone cement is polymethylmethacrylate, but other types will occur to those of skill in the art.
  • a common feature of many bone cements is that they have a viscosity such that substantial pressure can be required to effect expression of the bone cement from the syringe, through any connective tubing and the needle and into the vertebral cavity.
  • considerable care is required to reduce the likelihood of overfilling the vertebral body, as such overfilling can rupture the spinal cord and paralyze the patient.
  • Prior art syringes, connecting tubes and needles can in some circumstances impede controlled and careful injection of bone cement into the vertebral body due to irregularities found along the channel between the syringe body and the needle tip. Such irregularities can be found, in particular examples of prior art, at luer-lock junctions for removable connections between the syringe, the connecting tube and the needle. Further viscosities of non-polymethylmethacrylate cements are generally greater than the viscosity of polymethylmethacrylate's, and such viscosities can present problems at luer-lock junctions.
  • U.S. Pat. No. 6,488,667 to Murphy (“Murphy #2”) teaches a needle holder that can be used to allow the radiologist to grasp and control the needle during insertion into the vertebral body, while also allowing the radiologist to keep his or her hands farther away from the imaging beam than if the radiologist had to grasp the needle directly. While effective, one problem, however, with the needle holder in Murphy #2 is that in certain circumstances, the needle holder can slide along the length of the needle, which can interfere with the desired level of control over the needle.
  • a bone cement apparatus comprising a delivery reservoir for holding a bone cement and a needle for injecting the bone cement into a bone.
  • the apparatus also comprises a passageway interconnecting the reservoir and the needle, the passageway having substantially uniform dimensions.
  • the reservoir can be a syringe.
  • the passageway can include a connecting tube.
  • the passageway can include a connector for attaching the connecting tube to the delivery reservoir.
  • the bone cement can be polymethylmethacrylate.
  • FIG. 1 shows a bone cement delivery apparatus in accordance with an embodiment of the invention
  • FIG. 2 shows an exploded view of a portion of the apparatus of FIG. 1 ;
  • FIG. 3 shows a bone cement delivery apparatus in accordance with another embodiment of the invention
  • FIG. 4 shows an, exploded view of a needle in accordance with another embodiment of the invention.
  • FIG. 5 shows the needle of FIG. 4 when it is assembled
  • FIG. 6 shows a partial sectional view of the needle of FIGS. 4 and 5 ;
  • FIG. 7 shows a bottom isometric view of the needle of FIGS. 4-6 .
  • Apparatus 20 comprises a syringe 24 , a connector 28 and a connecting tube 32 .
  • Apparatus 20 is used to deliver bone cement as part of a bone augmentation procedure, and in a present embodiment the procedure is vertebroplasty.
  • Syringe 24 comprises a barrel 36 defining a chamber 40 through which a plunger 44 can pass in order to express a bone cement (not shown) from a distal tip 48 of syringe 24 .
  • Connector 28 provides a fitting which can be used to releasably couple syringe 24 to tube 32 , such that a channel between tip 48 and tube 32 is substantially uniform with a channel defined by tube 32 . Connector 28 will be discussed in greater detail below.
  • Tube 32 is made any suitable flexible material and has a length of from about 10 or about 15 centimeters (“cm”) to about 20 or about 30 cm; Tube 32 includes a proximal tip 52 that is releasably attachable to connector 28 , and a distal tip 56 that is releasably attachable to a vertebroplasty needle (not shown). Tips 52 and 56 are joined by a body 60 that defines a passage for communicating bone cement from syringe 24 and into a vertebroplasty needle.
  • Syringe 24 , connector 28 and tube 32 are made from known materials and have a general size and configuration that is suitable for deployment in a vertebroplasty procedure, subject to various specific features discussed herein.
  • One example of a generally known off-the-shelf configuration is the Cook Duro-ject Bone Cement Injector, available from COOK GROUP INCORPORATED, P.O. Box 489, Bloomington, Ind. 47402-0489, USA.
  • FIG. 2 a partial-sectional view of apparatus 20 shows distal tip 48 of syringe 24 , connector 28 , and proximal tip 52 of tube 32 in greater detail.
  • tip 48 defines a substantially uniform hollow cylindrical channel 64 having an interior diameter, the interior diameter being represented in FIG. 2 by the reference “D 1 ”.
  • D 1 is chosen according to the type of bone cement being expressed from chamber 40 . Where chamber 40 has a volume of about 10 cubic centimetres (“cc”), and where the bone cement is polymethlymethacrylate, then D 1 can be from about five millimeters (“mm”) to about fifteen mm; or D 1 can be from about seven mm to about twelve mm; or D 1 can be from about eight mm to about ten mm.
  • cc cubic centimetres
  • mm millimeters
  • D 1 can be from about seven mm to about twelve mm
  • D 1 can be from about eight mm to about ten mm.
  • other sizes of chamber 40 , dimensions of D 1 and/or choices for bone cement to be expressed from chamber 40 will now occur to those of skill in the art.
  • Tip 48 also includes a set of exterior threads 68 along the peripheral, external surface of tip 48 .
  • Tip 52 of tube 32 also includes a set of exterior threads 72 along the peripheral, external surface of tip 52 .
  • Tube 32 provides a passage 76 for carrying bone cement from syringe 24 to the vertebroplasty needle.
  • Passage 76 is substantially cylindrical and has a configuration and dimensions that are substantially the same as channel 64 .
  • passage 76 has interior diameter, the interior diameter being represented in FIG. 2 by the reference “D 2 ”.
  • Diameter D 2 is substantially the same as diameter D 1 .
  • Connector 28 is substantially cylindrical and has an external surface with a substantially uniform surface.
  • Connector 28 is characterized by a first set of interior threads 80 that are complementary to exterior threads 68 , such that tip 48 can be securely fastened within connector 28 by threading threads 68 and 80 together.
  • connector 28 is also characterized by a second set of interior threads 84 that are complementary to exterior threads 72 , such that tip 52 can be securely fastened within connector 28 by threading threads 72 and 84 together.
  • Connector is also characterized by an interior annular flange 88 .
  • Flange 88 thus presents a substantially cylindrical opening and has a configuration and dimensions that are substantially the same as channel 64 and passage 76 .
  • passage 76 has interior diameter, the interior diameter being represented in FIG. 2 by the reference “D 3 ”.
  • Diameter D 3 is substantially the same as diameters D 1 and D 2 .
  • each threads 68 and 80 , and threads 72 and 84 are chosen such that, when threads 68 and 80 are engaged, and threads 72 and 84 are engaged, rotation of syringe 24 (or tube 32 ) in a first direction will tighten all connections between syringe 24 , connector 28 and tube 32 ; while rotation in an opposite direction will loosen the connection between syringe 24 , connector 28 and tube 32 .
  • tighten means that tips 48 and 52 are urged towards flange 88
  • looseen means that tips 48 and 52 are urged away from flange 88 .
  • FIG. 3 shows a bone cement delivery apparatus 20 a .
  • Apparatus 20 a shares a number of common components with apparatus 20 , and like components include like references, but followed by the suffix “a”.
  • apparatus 20 a does not include a connector like connector 28 from apparatus 20 . Rather, the functionality of connector 28 is integral with tip 48 a .
  • Tip 48 a is provided with a channel 64 a having a first diameter, and a set of interior threads 84 a which are formed on an interior surface of tip 48 a having a second diameter greater than the first diameter. The second diameter corresponds with the outside diameter of tip 52 a . Threads 84 a are thus complementary to exterior threads 72 a of tip 52 a.
  • apparatus 20 will be assembled (similar to the assembled depiction of apparatus 20 a in FIG. 3 ) so that a substantially secure and sealed connection is made between syringe 24 and tube 32 . Syringe 24 and tube 32 are thus “tightened” within connector 28 , thereby providing a substantially uniform passage from chamber 40 to passage 76 .
  • plunger 44 is removed from barrel 36 and chamber 40 is filled with a bone cement. Plunger 44 is then reinserted into barrel 36 .
  • FIGS. 4-7 shows a needle 120 for use in a bone augmentation procedure.
  • apparatus 120 can be used in conjunction with apparatus 20 or apparatus 20 a .
  • Needle 120 includes a stylet 124 and a trocar 128 for receiving stylet 124 .
  • stylet 124 and trocar 128 provide a solid instrument for piercing a vertebral body, as is described in Murphy #2.
  • Stylet 124 is characterized by a shaft 132 with a piercing tip 136 and a grip 140 located on the end of shaft 132 opposite tip 136 .
  • Trocar 128 is characterized by a duct 144 and an open tip 148 and a handle 152 located on the end of duct 140 opposite tip 148 .
  • the overall configuration, size, length, and other features (such as length of shaft 132 and duct 140 or shape of the complementary tips 136 or 148 ) of stylet 124 and trocar 128 is not particularly limited and can be chosen according to the desired vertebroplasty or other bone augmentation procedure.
  • Tip 136 is receivable into an opening 156 located on handle 152 . Opening 156 is located on a cut-away section 160 of handle 152 . Cut-away section 160 is adjacent to a knob 164 that can be grasped. Cut-away section 160 is complementary in shape to grip 140 . As best seen in FIG. 5 , when stylet 124 is assembled to trocar 128 , grip 140 and handle 152 present a substantially solid, and contiguous mass that presents a striking surface for a hammer. As known to those skilled in the art, such a hammer is used to drive tips 136 and 148 into the vertebrae (or other bone location for which an augmentation procedure can be desired.)
  • Needle 120 also includes a lock for affixing grip 140 within cut-away section 160 .
  • the lock can take a variety of desired configurations, but in a present embodiment the lock includes a tab 168 located on grip 140 and a complementary groove 172 on handle 152 .
  • grip 140 can be rotated so as to engage tab 168 within groove 172 in a locked position.
  • tips 136 and 148 are aligned to present a contiguous piercing surface.
  • stylet 124 can be removed from trocar 128 .
  • Needle 120 also includes a holder 176 that is removably attachable to handle 152 .
  • handle 152 include a spherical socket 180 for receiving a ball 184 .
  • Ball 184 is substantially spherical and slightly smaller than socket 180 .
  • Ball 184 includes a protrusion 188 that itself includes a pair of arms 192 .
  • arms 192 fit into a complementary pair of grooves 196 located on holder 176 , so that that holder 176 can be removably attached to handle 152 .
  • Handle 152 also includes a tensioning mechanism 200 .
  • tensioning mechanism includes a set screw 204 that is rotatable so as to urge a pin 208 into, or out of, engagement with ball 184 .
  • ball 184 will either freely rotate within socket 180 , or be held in a substantially fixed location within ball 184 .
  • Adjusting screw 204 varies the amount of force applied to ball 184 , thereby affecting the amount of force that is applied to holder 176 to move holder 176 in relation to handle 152 .
  • needle 120 is shown connected to apparatus 20 a .
  • tube 32 a is shown connected to opening 156 .
  • a fitting to connect tube 32 a opening 156 is indicated at 212 .
  • Fitting 212 is configured in substantially the same manner as the fitting between tip 52 a and 48 a shown in FIG. 3 .
  • fitting 212 is thus structured to provide a secure fit between tube 32 a and needle 120 , while also providing a substantially uniform pathway for bone cement to travel.
  • handle 152 includes a passage 216 in communication with passage 76 a .
  • Passage 216 is substantially the same configuration and dimension as passage 76 a .
  • Duct 144 also includes a passage 220 in communication with passage 216 .
  • Passage 220 is substantially the same configuration and dimension as passage 216 .
  • Passage 220 is carried through an overall path of substantially the same dimensions and configuration when it travels through passages 216 and 220 , and eventually into the vertebral body. It will now be appreciated that when apparatus 20 a and needle 120 are used together, the bone cement is carried through a substantially uniform path from tip 48 a to tip 148 .
  • needle holder 120 can also be provided with (though need not be) a vibrator 224 .
  • vibrator 224 includes an imbalanced micromotor 226 , such as that commonly employed on a cellular telephone or wireless paging device.
  • Micromotor 226 is housed within handle 152 and is sized in order to provide a vibrating force to duct 144 and thereby facilitate the flow of bone cement through passage 216 and 220 , and thereby ease the infective force needed at plunger 44 a .
  • Micromotor 226 is powered by a battery 228 or other power supply housed within handle 152 , and selectively turned on or off via a power switch 232 operably connected to both micromotor 226 and battery 228 .
  • apparatus 20 or apparatus 20 a can be used with needle 120 .
  • needle 120 need not include vibrator 224 .
  • connection, fittings etc are shown for apparatus 20 and apparatus 20 a and holder 120 , (e.g. sets of complementary threads), a vast array of other fittings that will also achieve the result of a substantially uniform passage from a syringe (or other delivery reservoir) into a vertebral body (or other bone site) are within the scope of the invention. Indeed, a unitary construction along various points of the such a path can be employed in order to provide such a uniform path.
  • bone cements include hydroxy apetite, calcium phosphate, calcium sulphate, calcium hydroxy apetite, or any other cement that may integrate with bone and form new bone. Because of the respective viscosities of these cements are higher than polymethylmethacrylate's, a non-luer lock system is provided. Further, the present invention allows for injection of any cement at lower pressures.
